Jianhua,

I just tried loading RbdiPgSQL and then Rdbi and found these errors with Rdbi 
from the devel repository.  Any ideas on how to fix this?  I'm cc'ing the 
bioc-devel list in case there is something interesting to be learned from the 
discussion, given the state of namespaces.

Thanks,
Sean
Loading required package: Rdbi
Error in loadNamespace(package, c(which.lib.loc, lib.loc), keep.source = 
keep.source) :

Just looking a bit, it seems that Rdbi has this statement in 'zzz.R':
.onLoad <- function(lib, pkg) {
  # Changed by JZ from Rdbi.PgSQL to RdbiPgSQL
  autoload("PgSQL", "RdbiPgSQL")
# autoload("MySQL", "Rdbi.MySQL")
.....

And in RdbiPgSQL NAMESPACE:
import(Rdbi)

Is this causing the circular dependency?
